Hey fellas, so im having Powdery Mildew problem indoor and im looking for UV lamp, there are plenty different lamps and pricing need help with that, an opinion from someone who used any of that or who has more knowledge about them couse i have 0 knowledge and experience with UVC disinfection lamps. Dont want to spend 500$ on lamp and than figure out that it worthless in my situation for example variations from this web which is better to use: https://www.webhydroponics.com/category/pest-control-and-sterilization/cure-uv/

UVC will kill it however finding a happy medium and not torch your plants is the issue ....
too little or too much.

Although there is a handheld lamp available if I’m not mistaken.

I’ve had two 36w UVC lights,that I put in a wooden box with a fan on top drawing the air out...and have not seen any pm since plugging it in 2 months ago.
As far as killing everything it touches my plants are just fine...the units I have are designed to be in the hvac system..

26~28celsius, 40~60% humidity depends on weather outside. But there was few very hot days, outside there was like +34 celsius maybe. Plants were sleeping in +30 celsius couldn’t get any lower temperature

Oh now im starting to understand, it’s not usable direct light on plants it’s for air filtering around them? So i can buy this lamp in amazon put it in the box with fan and filter air in the room and fungus thats left on leafs just take them off and that’s it? I dont need to use direct light on plants? I’ve never done this before and today is the first time i herd about this UV disinfection thing :)
